SHOE AND METHOD OF MAKING THE SAME Filed May 2, 1927 /N|/ENTUR 22 4 I Patented June 24, 1930 UNITED STATES PATENT OFFICE EUGENE J. BAY, OF BEVERLY, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MA- CHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY SHOE AND METHOD OF MAKING THE SAME Application filed May 2, 1927.

This invention relates to the manufacture of shoes. It is herein exemplified as applied to the manufacture of standardized shoes in which various parts or units, while they are being assembled and secured together, are

jijgged, or relatively positioned, by the use 16 but the invention is not limited to use in connection with shoes of that type.

More specificall the invention relates to a novel heel pa to a shoe having such a pad incorporated therein, and to a method of locating it accurately and retaining it effectively in its proper position in the shoe.

In most-shoes the heels are attached by nails or other fastenin s that penetrate to and usually are clinche upon theinner face of the insole and, therefore, it is usual to attach to the upper face of the heel portion of the insole by an adhesive a relatively thick pad of sheet felt, leather, imitation leather or the like to protect the foot of the wearer. Accordin to the present invention, a pad, which is provided for the shoe, fulfills the well known protective function just mentioned in a superior manner and it also serves additional useful functions. For example, the illustrated pad is made'of such material and of such s ape as to fit, and provide a support for, the heel of the wearer and also, at its under face and curved edge, to fit the adjacent interior surface of the heel portion of the shoe. Preferably it terminates in a feather edge at its forward end and has a gradually increasing thickness longitudinally up to a maximum in the vicinity of the juncture of the body of the pad and an upstanding marginal flange.

A further and important feature of the illustrated heel pad is that it is provided Serial No. 188,219.

with one or more projections formed and located to engage corresponding recesses in the heel end of the shoe. Preferably, these pro ections. are provided by two substantially conical jig pins integral with the body of the pad, projecting from its under face and so located as to engage and fit tightly at their bases corresponding cylindrical jig holes in the heel portion of the insole. Such a pad may conveniently be made of rubber and shaped in molds to approximately the desired outline and of varying thickness. The frlctional grip of the jig pins upon the walls of the 'ig holes can be relied upon normally to retain the pad in place without requlring the use of any adhesive. Moreover, the ig pins also have the function of plugging or tightly closing the jig holes and tend to keep out from the interior of the shoe any moisture which may work its way into the jig holes which are provided 1n the heels according to the method set forth in the lVarren application above referred to.

The invention in its preferred embodiment and as it will preferably be practiced in the manufacture of shoes will now be de scribed in detail with the aid of the accompanying drawings and will then be defined in t e appended claims.

In the drawings,

Fig. 1 is a view in perspective of the novel heel pad viewed at its upper face,

Fig. 2 is a similar view viewed at its Fig. 4 is a central longitudinal section of I the rear portion of a shoe in which the heel pad has been incorporated according to the method which constitutes the invention in one aspect.

The shoe illustrated is of a general type fully disclosed in the Warren application above referred to and includes an upper indicated generally by the numeral 10 and comprising a lining 12, an upper 14, a backstay 15 and a counter 16. 18 indicates an insole, 20 a short outsole, and 22 a heel made up, as illustrated, of a heel base 24 forepart and shank filler 30 and a metallic .shank stiffener 32. A heel filler piece is indicated at 34. The upper materials, including the counter, are securely fastened to the insole 18 by a series of tacks indicated at 40, which as shown have their points clinched at the inner face of the insole. The heel base 24 is secured to the remainder of the shoe by a series of attaching nails 42 which also, as shown, are clinched at the inner face of the insole. The rubber top section 26 is likewise secured to the heel base and to the shoe by attaching nails 44 Which may or may not be clinched on the insole. As fully explained in the said W'arren application, the heel 22 is provided with a pair of jig holes 46 terminating short of the tread face of the heel and the insole is provided with a corresponding and alining pair of jig holes 48, these holes extending also through other elements of the shoe as illustrated and performing important jigging functions in the assembly of such elements and in other steps in the manufacture of the shoe.

The novel heel pad provided by this invention is designated generally by the number 50. It may be of any suitable material, preferably one which can be readily molded such as fairly hard and tough rubber. As illustrated in the drawings the body of the pad terminates in a marginal tapering flange 52 at the sides and rear and in a feather edge at its front end 54 so that its thickness gradually increases longitudinally to a maximum at a point indicated at 56 in the vicinity of the juncture of the body of the pad with said flange although, as clearly shown in Figs. 3 and 4, the flange merges at its upper face into the body of the pad. Moreover, the thickness of the pad transversely gradually increases from the longitudinal axis thereof outwardly. Thus the upper face of the ad forms a continuous, smooth, upper surfhce for engagement by the foot or heel of the wearer. Exteriorly the flange 52 forms an oblique angle with the bottom face of the pad, the two surfaces meeting in a line 58, so that the exterior of the pad closely fits the corresponding interior surface of the shoe. Projecting from the under face of the pad are two integral, substantially conical projections or jig pins 60 which are located in a predetermined relation to the edges 54, 58 of the pad and are constructed and arranged to enter and tightly fit at their bases the jig holes 48 in the insole 18.

Thus, in the manufacture of the shoe after the heel has been attached in the manner above described and as illustrated in Fig. 4, the heel pad, as shown in Figs. 1 to 8, 1S assembled with the shoe by inserting the pins 60 into the holes 48 of the insole. The relative diameters of the pins and of the holes are such that the pins attheir bases, tightly fit the cylindrical holes in the insole. Thus the pad not only is located with absolute accuracy in its proper position in the shoe but it is normally retained in that position by the friction of the pins with the walls of the holes and, to some extent, by the natural adhesion of the insole and lining with the closely fitting pad.
